Abstract:

【Objective】 The aim of this study was to explore the influence of different habitats on the accumulation of polypentenol, soluble sugar, soluble protein and lipids in ginkgo(Ginkgo biloba) leaves, and to identify the main site factors affecting the accumulation of metabolites to provide a theoretical basis for ginkgo cultivation. 【Method】 Using a randomized block experiment design and variance analysis, multiple comparisons, correlation analysis and regression analysis methods, the changes in polypenol, soluble sugar, protein and lipids in the leaves of two ginkgo(female and male) were studied across seven habitats. 【Result】 (1) There were significant differences in the contents of polyphenol, soluble sugar, protein and lipids of ginkgo leaves across the different habitats (P <0.05). The contents of polyphenol, soluble sugar, soluble protein and lipids in samples from Shijiazhuang were the highest. (2) There was a significant positive correlation (P <0.01) between the content of polyphenol enol and lipids, but a significant negative correlation (P <0.05) between the content of polyphenol enol and protein. (3) The mean warmest month temperature was the main factor affecting the accumulation of polyphenol, soluble sugar, soluble protein and lipids in ginkgo leaves. In addition, sunlit time and the content of P and K in the soil also had a significant effect on their accumulation in ginkgo leaves. 【Conclusion】 Environmental factors can significantly affect the metabolite content of ginkgo leaves. A warm environment is conducive to the biosynthesis and accumulation of lipids such as polyamylenol.
